2: Evaluation Kit
The xPico Embedded Device Server family of products can be evaluated using several
available Evaluation Kits depending upon the type of PCB mounting and interface.
The xPico Embedded Device Server Evaluation Kit (part number XPW100100K-01) is for
evaluating the xPico and xPico Wi-Fi modules with 40-pin connector interface. The xPico Wi-Fi
SMT module with on module antenna (XPCW1003100) module uses the XPCW1003100K.
The xPico Wi-Fi SMT module with U.FL connector comes on a carrier board that uses the
same board as the used for the connector versions of the module. This Evaluation Kit is the
XPCW1002100K. All of these kits can help
you get familiar with your xPico module so that you
may understand how to integrate your
xPico embedded device server into a given product
design.

Evaluation Board Description
The xPico Wi-Fi evaluation board provides a test platform for the Lantronix xPico device
server
products. The evaluation board uses either 5V power from a USB device port
connector or
power supplied to the Ethernet connector via PoE (XPW100100K-01 only). The evaluation
board also
provides a header for connection to a 2.2V to 5.5V external source, such as a
battery. The
Evaluation Kit includes a 5V wall adapter with a USB plug to allow powering the
evaluation
board from a standard power strip. The evaluation board includes all necessary
regulators to
power the 3.3V xPico module. The evaluation board has the following features:
One DB9 serial port connector with a multi-protocol RS232, RS422, RS485 transceiver at
rates up to 1Mbps. Serial port modes are configured by on-board jumpers. The xPico Wi-
Fi does not support RS485. RS485 is applicable only to the xPico.
A second RS232 serial port is available on a header.
One RJ45 10/100 Ethernet port with an integrated PoE regulator to allow powering from
standard POE PSE. (POE works with Ethernet xPico modules only) ( XPW100100K-01
only)
One Mini-Type B USB device port connector for 5V input power. This port also has an
integrated USB-to-serial converter. The USB-to-serial converter can be connected to the
xPico second serial port via a board jumper setting.
A second Mini-type B USB device port is available for connection to the xPico module

USB device port. (Currently available on xPico Wi-Fi only)
LEDs for the xPico Ethernet, WLAN, and System status outputs along with two additional
LEDs that can be driven via jumper wire are provided.
Access to all logic level IO signals on the xPico via header pins for measurements and
connections to other places.
The figure below shows the xPico evaluation board and highlights all of the various
connectors
and configuration jumpers. The following table lists each of the connectors and
jumper
headers along with their function. Further description and pin assignments are

All of the xPico module serial port signals can be used as configurable pins. Jumper headers
JP17, JP8 and JP9 have been included to allow for each of the serial port signals to be
connected or disconnected from the serial port transceiver. The tables below list the JP17,
JP8, and JP9 serial port signal connections. Install jumper or remove as needed for desired
function. In addition, the second serial port on the xPico module can be connected to either the
serial port on J18 or to the USB on J5 via the on board USB-to-serial converter. Jumpers JP8
and JP9 allow for the selection of sending the JP18 or J5 USB-to-Serial converter to Serial Port 1.
In order to access the unit through the J5 USB port, you will need to install the USB-to-serial
VCP driver from FTDI on your PC. It is available in the installation directory of DeviceInstaller
and later versions, for installation. It can also be obtained from the FTDI website provided
below. Once installed, you will be able to view the xPico boot messages as well as provide
command inputs through any PC terminal program, such as Tera Term.

Antenna Port
The xPico evaluation boards (XPW100100K-01 and XPCW1002100K ) includes a bracket for
mounting the U.FL to Reverse Polarity SMA RF cable included with the kit. Follow the
procedure below when installing the antenna cable. The same procedure applies when using
the PCB strip antenna, with the exception that the swivel antenna does not need to be
connected to the RF cable.
1. Attach the U.FL cable to the antenna prior to installing the xPico Wi-Fi module on the
J1
socket.
2. Attach the plastic mounting clip to the module.
3. Install the module/SMT module on carrier board into the J1 socket.
4. Install the external antenna to the SMA end of the RF cable.
Note: Install or remove the antenna connections only while the module is powered
off.

Ethernet Port
The xPico evaluation board XPW100100K-01 includes one RJ45 with on-board magnetics for
connection to the
xPico module 10/100Mbps Ethernet interface. Connector J2 is the Ethernet
port.
Note: The Ethernet port is functional for xPico Ethernet modules only.
Power Supply
The evaluation board provides several options for input power. Included with the kit is a 5V
wall adapter. The 5V wall adapter plugs into USB connector J5. In addition to powering from
the wall adapter, the evaluation board can be powered from a standard PC USB Host port by
connecting a USB cable between the PC and J5 or J6. The XPW100100K-01 evaluation board
can also be
powered via Power-Over-Ethernet (PoE). The integrated PoE regulator accepts
power from
the Ethernet port on J2. The final option is to connect DC power to header JP19.
